Scola, 33, adds frontcourt depth to a team that's intent on challenging the Miami Heat in the Eastern Conference. He averaged 12.8 points and 6.6 rebounds while playing in all 82 games for the Suns last season. Those were off his career averages of 14.2 points 7.5 rebounds.

The Argentinian has two years and $9 million remaining on his contract. He figures to replace Tyler Hansbrough in the Pacers' rotation; the Pacers rescinded a qualifying offer to Hansbrough earlier this month and he has since signed with the Toronto Raptors.

Scola spent the first five seasons of his NBA career with the Houston Rockets before joining the Suns last year.

Green, a 6-8 swingman, average 7.0 and 2.4 rebounds in his only season with the Pacers. In 2011-12, he'd averaged nearly 13 points for the Nets after three seasons out of the league. Plumlee, a 6-11 power forward, appeared in 14 games as a rookie last season.
